WATER-COOLER.

SPECIFICATION forming part of Letters Patent No. 235,696, dated December21, 1880.

ApplicationledOctober26,1880. (No model.) 4

To all 'whom tt may concern Be it known that I, THOMAS D. MowLns, acitizen ofthe United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Water-Coolers, and I do hereby declare thefollowing to be a full, clear, and exact description or" the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

My invention relates to improvements in water-coolers for which LettersPatentNo. 224,7] 2 were granted me February l2, 1880, in which only asmall quantity of water is kept on the ice and this supply automaticallyrenewed as needed.

The objects of my improvements are, first, to provide a secure andeasily-adjusted airtight cover for the icechamber; second, to draw offany surplus water made by the melting of the ice in the ice-chamber. Iattain these objects by the mechanism illustrated in the accompanyingdrawings.

Figure 1 is a plan of the cooler; Fig. 2, a vertical transversesectional view of the same; Fig. 3, a view of the spigot as turned onfor drawing oft water. Y

N is the chamber for the ice; K, lump of ice therein; M M, packingaround the ice-chamber; L L, reservoir for the additional supply ofwater; F F, a movable cover, made on the principle of the diving-bell,and lit-ting snugly over the outside of the ice-chamber, and at the sametime covering over the top of the supplytube B. This top reaches to thebottom of the reservoir L, and is held in position by the snugt; or, ifnecessary, any suitable fastent ing may be adjusted. H H are the wallsof the icechamber5 A G, an ordinary bib-cock for drawing oi" water, ofwhich A is the tube and 4Gr is the plug. The bearing` in the cock ismade to extend some considerable distance up and around the plug, (seeFig. 3,) and the plug has a small opening therein, said opening beingashort distance above and running parallel with the water-way. Throughthe bearing, on both sides, is also a small opening', to correspon dwith the hole in the plug, so that when the cock is turned to draw offwater the opening through the plug G and the openings in the bearing areon a line with the tube DD, as shown by the dotted line in Fig. 3. I isthe second waterway in the side of the cock, (not in the plug, thathaving one water-way only,) to which ,0n either side, are attached thetubes B and C; D D, an air-tube extending from the inside of theice-chamber, above the water-line, to and connecting with the opening inthe bearing ot' the plug G; E E, an air-tube extending from the outerrim of the cooler to a point in the ice-chamber desired for awater-line; B B, a tube for conveying the water from the reservoir L tothe plug G, through which it passes into the tube G and thence into theice-chamber N.

The manner of operating the cooler is as follows, viz: The ice beingfirst introduced,

the cover F F is placed over the top of the` ice-chamber N and tube B.The water is then poured into the reservoir L L. The bottom edge ofthecover not being water-tight, the water iows up to the top of and downthrough the tube B, through the plug G and tube C into the chamber N,the airin the ice-chamber being, by the pressure of water, forced outthrough the tube E until the opening inside the ice-chamber is sealed bythe water rising above it; then, as no more air can escape no more watercan iow in, and the water stands on a level with the top of the tube Euntil the ice begins to melt, when the volume of water is increasedcorrespondingly. This extra supply, made by the melting of the ice, isdrawn oit' thus: The plug Gr being turned for drawing off water, thesaine motion shuts the opening I and allows no water4 toilow from thereservoir L through thetubes B and Cinto the ice-chamber; consequentlyany water drawn oli' must reduce the quantityin said ice-chamber. At thesame time and by the same movement of turning the cock for drawing waterthe air-tube D D is opened, thus allowing air to rush in and fill thevacancy made. by the water drawn ofi'. When sufficient water has beendrawn the motion of shutting 0E the water shuts the air-tube D and opensthe connection between the supply-tubes B and C and the reservoir L; butno water can ow Ainto the IOO ice-chamber unless the drawing off hasreduced the Water therein below the air-tube E, in which ease the airwould be foreed out and the Water would again ow in until it had sealedthe air-tub'e E by rising above the openlng.

As the top of the supply-tube B extends some distance above the bottomof the reser- Voir L the Water iiowing into the iee-ehamber is n ottaken 'from the bottom of said reservoir; consequently'the greater partof any sediment or impurities contained in the Water will settle and bedeposited on the bottom of the reser- Voir, and not enter theice-chamber at all.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. In a Water-cooler, the combination of the reservoir L, theice-chamber N, the tube B, connecting with the twoavay cock A G, and thecover F, constructed and operating substantially as and for the purposesset forth.

2. In a water-cooler, the combination of the two-Way oook A G, tubes Band C, ice-chamber N, air-tube H, reservoir L, and cover F, constructedand operating substantially as and for thepurposes set forth.

3. In a water-Cooler, the combination of the air-tube E, ice-chamber N,cover M, tube B, and reservoir L, constructed and operatingsubstantially as and for the purposes set forth.

4. In a Water-cooler, the supply-tube B, extending above the bottom ofthe reservoir L, in combination with the ice-chamber N and the tube Aand plug G, substantially as set forth.

5. In a water-cooler, the air-tight cover F, in combination with theice-chamber N, reser- Voir L, and tube B, substantially as and for thepurposes set forth.

In testimony whereof I atlx my signature in presence of two Witnesses.
